Safe to Switch Filters? Hi guys. I have recently bought a 10 gallon aquarium starter kit, and it came with a filter. This filter was the Tetra Whisper In-Tank Power Aquarium Filter. I have already set up my tank since Friday and was wondering if I could switch the filters. I want to switch to the Aqueon Quiet Flow 10 Aquarium Power Filter. Could I do this? Would this be a problem? If I can do this, how would I change the filters?
